Improvement in insulators for telegraph-lines



UNITED STATES PATENT QFFICE.

ISAAC I. TATOM, OF WEST POINT, GEORGIA.

IMPROVEMENT IN INSULATORS FOR TELEGRAPH-LINES.

Specification forming part of Letters Patent No. 139,436, dated May 27,1873; application filed December 7, 1872.

To all whom it may concern:

Be it known that I, ISAAC I. TATOM, of West Point, in the county ofTroup and State of Georgia, have invented a new and valuable Improvementin Telegraph-Insulators and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings makinga part ofthis specification, and to the letters and fig ures of reference markedthereon.

Figure 1 of the drawings is a vertical longitudinal section of myinsulator. Fig. 2 is a transverse section of same.

This invention has relation to telegraph-insulators; and it consists inthe novel construc tion and arrangement of the parts constituting aninsulator, as hereinafter described and claimed. 7

A in the drawings represents the glass insulator or spool, made in twosemi-cylindrical sections, and having a central aperture through whichthe Wire it passes. B designates the peg or frame to which the insulatoris applied. Said frame or peg has a threaded shank, D, to be used inattaching it to a telegraph-pole or other object. The upper part of thepeg is constructed with a tenonor offset, a, to the shoulder b of whichis hinged the block 0. The parts a c are corrrespondingly recessed topro vide a cylindrical cavity for the reception of the insulator, whichis therein retained by the end flanges d. A shouldered latch, c, whichis hinged to the upper end of the block or cov er 0, iits a mortise orslot cut in the top of the part a, and serves thus to retain the parts a0 together.

The insulator, it will be seen, may be easily inserted in or removedfrom its socket when desired.

Sometimes I construct the peg without the flanges d, but use aninsulator or spool having end flanges, which flanges prevent end play.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

The insulator having the frame B provided at its lower end with thethreaded shank D, and its upper end having the offset a and shoulder b,hinged block 0, with the shouldered latch c, all constructed andoperating in the manner shown and described.

In testimony that I claim the above I have hereunto subscribed my nameinthe presence of two witnesses.

I. I. TATOM.
